when were red cards introduced in football

Red cards were introduced in football in 1970 , first used at the FIFA World Cup in Mexico. The idea came after confusion in a 1966 World Cup match showed referees needed a clearer, universal way to signal discipline.

Quick scoop

• Before 1970: referees used verbal warnings and dismissals.
• 1970: yellow and red cards were introduced at the World Cup.
• First club-level use in England: 1976, in the English Football League.

Why they were added

The card system made referee decisions easier to understand across different languages, since the meaning of colors is obvious and instant. That’s why the red card became one of football’s most recognizable signals.
